A: Since this unit is designed for indoor installation (like a basement or utility room), it pulls heat from your indoor air.

While both are efficient, the Rinnai REHP is the superior choice for Ontario homeowners for several strategic reasons:
Maintenance Design: Rinnai features horizontal air filter placement for quick, tool-free cleaning.
Most Ontario homeowners switching from a standard electric water heater save between $300–$500 annually on electricity, depending on usage patterns.
